Determing object location in Unity 3D

Question

I've been learning Unity 3D, slowly. I'm trying to make a maze, and need an event to occur when they reach the finish area.

How do I fetch object location and check if it's in the target area? Using Javascript.

Thanks for any help!

Answer 1

If your end area can be treated as a box, you could add a BoxCollider to your scene around the finish area and set its isTrigger property to true. Then you'll get a callback to OnTriggerEnter on your entity when it enters the area, which you can subsequently use to end the level or whatever.

Answer 2

As Peter G states on Unity Answers:

If you have a rigidbody, then you can do Rigidbody.IsSleeping() to check if your rigidbody is sleeping

If you are using a Character Controller, then checking to see if CharacterController.velocity == Vector3.zero;

Or, you can manually save a Vector3 every frame that remembers the last position. Something like:

function Update () {
 curPos = position;
 if(curPos == lastPos) {
     print("Not moving");
 }
 lastPos = curPos;
}

Answer 3

well if you by target area you mean the finish area then you can do this in several ways

you can use collides

in a simple way : (1) create a plane , create a tag named "finish" (2) then select the player then click the dropdown "tag" in the inspector . search for "finish" and select it . you will also need to add a collider to your gameobject.

then create a new JavaScript and add this code to it

    function OnCollisionEnter(collision : Collision){
    if(collision.gameObject.tag == "finish"){ 

//"STOP GAMEOBJECT FROM MOVING"
}

}

or use this method

place this script on your player . this script is probably just as god as using colliders for what you are doing

 var other : Transform;
    function Update ()
    {

    var dist = Vector3.Distance(other.position, transform.position);

    if (dist < 100)
    {
    //stop player movent here 
// move player to exact finish position over time 

    }

    }
